The lower heat-sealing member 3 is fixedly installed on the machine base 1 to provide heat-sealing operation. The upper heat-sealing member 2 is rotatably connected to the machine base 1 and is connected to the foot-operated assembly 4. When the operator steps on the foot-operated assembly 4, the upper heat-sealing member 2 can be moved closer to the lower heat-sealing member 3, thereby realizing the upper and lower heat-sealing operations. When the operator releases the foot-operated assembly 4, the upper heat-sealing member 2 moves upward until it is reset.

[0017] Furthermore, an adjustment component 5 is provided on the mounting plate 31, which can conveniently adjust the height of the supporting plate 32, so as to adapt to the use of operators of different heights.

[0018] Furthermore, a carrying groove 33 is opened in the middle of the carrying plate 32, which can facilitate the operator to stack the items that need hot air in the carrying groove 33, and through the design of the driving component 6, the items can be limited to the left and right, thereby ensuring the stability of the placement process, and when placing bags, it can also avoid their scattering.

[0019] The mounting plate 31 is provided with a first sliding groove 311 and a second sliding groove 312 along its height direction, and the supporting plate 32 is provided with a first sliding arm and a second sliding arm.
